This Otogirisou booklet is really cool! Not only does it feature a short manga adaptation of the game but it also contains a bunch of cute art and interviews with the creators. I especially love this cartoon demonstrating the "ideal" way to experience Otogirisou.
Some pages from the Otogirsou Treasured Book, a supplemental magazine edition included with a copy of Marukatsu Super Famicom, March 1992 (archive.org/details/otog...) #otogirisou #弟切草
